environmentally benign protocol for the aqueous synthesis of 1,2‐azidoalcohols via regioselective ring opening of 1,2‐epoxides using PEG‐MDIL as a novel magnetic phase transfer catalyst is described. The catalyst was studied by UV spectroscopy, IR spectroscopy, and thermogravimetric analysis. The reactions occur in water and furnish the corresponding azidoalcoholes in high yields. No evidence for the formation
描述了一种简单且对环境无害的方案,该方案通过使用PEG-MDIL作为新型磁性相转移催化剂,通过1,2-环氧化物的区域选择性开环来水合合成1,2-叠氮醇。通过紫外光谱,红外光谱和热重分析研究了该催化剂。反应在水中发生,并以高收率提供相应的叠氮孔。没有证据表明形成了副产物,并且未经进一步纯化就以纯净形式获得了产物。
